“We don’t yet understand the mechanisms involved — it could be an increased inflammatory response, direct brain modulation by the parasite, or even reverse causation where aggressive individuals tend to have more cats or eat more undercooked meat”.
The study looked at 358 adults, and found that chronic latent infection with T. gondii is associated with intermittent explosive disorder and increased aggression. Antibodies were collected between 1991 and 2008.
University of Chicago researchers say a parasite commonly spread from cats to humans may play a role in impulsive aggression. Approximately 16 percent of those in a “other psychiatric conditions” organisation had a infection, though reported identical exam scores in charge to a healthy group.
